First Crusade

The First Crusade was a joint expedition by Christendom in Europe with the aim of "liberating" the Holy Land from the Turks and other small Islamic sultanates who had taken it over in the past four centuries. The People's Crusade is sometimes considered a campaign of the First Crusade, as is the war with Coloman I of Hungary. The crusade ended with the capture of the Holy Land, nicknamed "Outremer" by the Franks, and the extermination of the people of Jerusalem, which became the Kingdom of Jerusalem. Other crusader states created were the Kingdom of Antioch, Kingdom of Tripoli, and Kingdom of Edessa.
